Most recovery systems on suction dredges use fixed riffles to trap gold out of lighter streambed materials as they are washed through a sluice box by a flow of water. Riffles are baffle-like obstructions, fixed in place along the bottom of the sluice box.

ContactMost sluice boxes use riffles or obstructions blocking free flow of gravel and sand from being washed out of the sluice box.
